Fix inventory showing quantities set to 0 (#239)

# Description

Please include a summary of the change and which issue is fixed. Please also include relevant motivation and context. List any dependencies that are required for this change.

- Fix a bug where the inventory would show a "x0" quantity when there were entities in the database with a current quantity of 0.
- This occurs when you sacrifice cards, that command can't delete the row as it has claims connected to it in another table, so we need to maintain that key.
